Good Quality Bass by Kenwood

Not everyone is looking for window shattering bass, some of us just want enough bass to enhance the all around sound of our car audio systems. Kenwood's KFC-W112S 12" Single 8-ohm subwoofer allows you to do just that. This subwoofer is meant to be paired up with a second KFC-W112S subwoofer, and wired in parallel to a final impedance of 4 ohms. The advantage here is that you are able to run two subs at a 4 ohm impedance which is more stable and produces a cleaner output with less thermal discharge from the amplifier. Also by having this subwoofer paired with a second you increase the amount of air that is being moved which in turn creates a deeper sounding bass. The polypropylene injection molded woofer cone and urethane surround provide rigidity and stability. So if you are looking to add some bass at a stable impedance, without spending a bundle, then two of these subwoofers are the perfect match for you.

Subwoofer Specifications

Subwoofer Series

Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.

Performance (Kenwood)

Subwoofer Size

Refers to the diameter of the subwoofer, measured in inches.

12"

Peak Power Handling

Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.

800 watts

RMS Power Handling

The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.

200 watts

Voice Coil(s)

Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.

Single

Impedance (Per Voice Coil)

The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.

8 ohms

Frequency Response

The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).

28 - 800 Hz

Sensitivity

An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".

90 dB

Xmax (millimeters)

Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.

7.7 mm

Subwoofer Design

This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle

Main Cone Color

This is the color of the speaker's or subwoofer's cone.

Black

Woofer Composition

Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.

Polypropylene

Woofer Surround

A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.

Urethane

Subwoofer Grille

Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.

No

Re-Cone Kit Available

Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.

No

Recommended Enclosure Specifications

Recommended Enclosure Type

This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / VentedSealed

Minimum Sealed Box Volume

This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.

0.8 cubic feet

Maximum Sealed Box Volume

This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.

1.75 cubic feet

Minimum Ported Box Volume

This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.

1.0 cubic feet

Maximum Ported Box Volume

This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.

2.0 cubic feet

Top-Mount Depth

The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.

5-9/16"

Cutout Diameter

The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.

10-13/16"

Shallow Mount Installation

This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

This is a great subwoofer. I have 2 powered by a 1600W amp. It's fairly cheap for the brand too. It's hits really hard and people hear me coming down the street. If you're looking for a woofer with deep, thick bass than this is the right thing to buy.

I bought these subs about a week ago and have em wired to a 1600w amp and let me tell ya i've never been so surprised. These are the best your gonna get for the price. Especially if you're ballin on a budget like me.

I have two of these in a sealed enclosure and they hit hard! I have them bridge with a 1600 watt amp that goes perfectly with them. The clarity and range of the bass is impeccable! For the price this is a must have for beginners and novices alike!

Great subs for an intermediate. Once you enter into the world of subs, you crave more and more power. I would say these are the middle step with 200 rms/ 800watts peak. Make sure to have an amp in the same rms neighborhood so you don't blow them!

I built a custom box for 2 into the back of my 03 Mustang GT Convertible and HOLY S***! These things pound! I have a 1000 watt amp on them bridged and it is so crazy loud and I haven't turned the amp more than halfway up yet. The sound quality is amazing! No distortion at all. Sonic got them to me in 4 days. And I am very pleased with them. If u want loud subs with good quality for a low price u have to get these!!!

There is no right answer to your question. Soon you will see many people chime in with MANY different configurations. Here are my suggestions - Assuming ONE sub & considering the sub is asking for 200w RMS @ 8ohms:
